Application filed Becember 23, 1918.

To all whom it may concrn:

Be it known that EDsoN L BEARDSLEY, a citizen of the United States, residing at Columbus, in the County OfFl'lDlllll and State of Ohio, has invented certain new and SB- tul Tmprovements in Valve-Litters, of which the following is a specification.

This invention relates to valve lit'ters and is designed particularly to render the task of removing or grindng valves comparatively easy.

The main object of my present invcntion resides in a structure whereby the cotter pin or similar structure holding the seating springs of the valves in conjunction with the valve stems may be readily removed and to then permit the complete removal of the valves themselves if desirable without removing the tool or litter from its applied position. In other words, if it is desired so to do, the lifter may be permitted to remain in its applied position until after the valves have been properly ground and the spring then placed in its operative position.

In this connection, my invention resides also as a further improvement over the structure shown in my previous Patent Number 1341,&88 granted October 2, 1917. In said patent, it was necessary to remove the tool from its applied position in order to permit removal of the valve but in the present einbodiment, this is rendered unnecessary.

The preterred embodiment of my invention is shown in the accompanying sheet of drawings in which similar characters of reference designate corresponding parts and in which,

Figure l illustrates my improved lifter partially in section and partially in side elevation and associated with the common type of valve,

Fig. 2 is a front view of the structure shown in Fig. 1,

Fig. 3 is a top plan view of the structure shown in Fig. 1 but detached from association with the engine parts,

Fig. l is a fragmentary perspective ot the outer end of the valve spring engagng leg of the yoke structure, and

Fig. 5 is a view in perspectii 'e of the supplemental valve spring engaging element.

In Figs. l and 2, I have attempted to only diagrammatcally illustrate a portion ot an internal combustion engine, one designating a body portion thereef in which are suitably monnted the valves 2 each provided with a Specification of Letters Patent.

atom 3 and then encircling seating spring 'in The lower end or" these sprin's bear directly upon the washers shown at 5 and these latter are held in their properly applied positions by means of the cotterpins 6. In grinding these valves, it isnecessary that the springs be compressed to pernit renioval of the cotter pins 6 so that the valve stems may be elevated suiiciently to permit the removal of their tappet rods.

l n order to accomplish the above, I have provided a yoke member 7 soinewhat similar in form to that illustrated in my patent mentioned above, this yoke member being completed by the upper leg S and the lower leg 9. Te the end of the upper leg, there is pivotally Secured at 10 a cam lever ll so arranged that, when the hump portion 12 is brought into engagement with the engine parts as shown in broken linos, the lower leg 9 will be elevated to compress the spring 4-. This lower leg 9 is cut out as shown at 13 to present a spring engaging portion but which in reality engages or forms seat for the washer 5. This leg is also provided with a tongue l l struck therefrom to extend in an iup'ight position and this tongue is designed to coperate with a complemental opening 15 forined in the supplemental valve spring engaging element 16. This element 16 is provided with a compressed portion 18 designed to seat in the forward end of leg 9 and when thus seated, is prevented ;From dislodgment by means of the tongue l l which,

passes through the opening 15. This supplemental element is also provided with a pair of symmetrically spaced valve spring engaging portions 17 and when seated upon the leg 9, this element occupies the position as illustrated in Fig. 2. In this figure, it will be apparent that two valve springs may be simultaneously compressed and that the cam 11 rests upon the engine trame work and not upon the valve heads 2. Thus when the tool assumes the position illust'ated in broken lines of Fig. 1, the two sets of springs are compressed which permits the removal oi: their respective cotter pins 6 and the subsequent removal or grinding of the valves 2 without of necessity removing the tool from its operative position. In this mannor, considerable time and labor saved.

lVhat I 'claim is:

l. In a valve lifter, a yoke structure, means at the top ot said structure to cause its elevation, an inwardly extending Il. 1 O

forniing a portion of said structure, said leg having a single valve spring engagng portion, and a supplemental element provided With a plurality of spaced valve spring en gaging portions seated on said leg.

2. In a valve lifter, a yoke structure, means at the top of said structure to cause its elevation, an inWardly extending leg 'orming a portion of said structure, said leg having a single valve spring engagng portion, and a supplemental element provided With a plurality of spaced valve spring engaging portions, said element being also provided With a seat to fit the valve spring engaging portion of said leg.

3. In a valve lifter, a yoke structure, means at the top of said structure to cause its elevation, an invvardly eXtending leg forning a portion of said structure, said leg having a single valve spring engaging portion,

an upwardly projecting tongue carried by said leg, and a supplemental element having an opening to fit said tongue and provided With a plurality of spaced valve spring engaging portions, said element being also provided With a seat to fit the valve spring engag'ing portion of said leg,

In testimony Whereof I afiix my signature.
